  • Patent number: 4712261
    Abstract: A mattress guard is disclosed for use in a convertible sofa bed having an air inflatable mattress supported on the mattress support of a folding bed mechanism frame. The mattress guard includes a pair of flexible guard members adapted to be placed on opposed edges of the mattress, elastic straps resiliently securing the guard members together along the top surface of the mattress and attachment devices for securing the guard members to the mattress support below the mattress. The guard members hold the bedding for the mattress securely against the mattress and prevent it from becoming entrapped in the folding mechanism when the bed is folded. In addition the mattress, will be compressed when air is released therefrom prior to folding of the sofa bed to space its edges away from the mechanism.

  • Patent number: 4596618
    Abstract: Disposable fitted sheets and method for making them. The sheets are formed without necessitating prior cutting by folding edges of the material and attaching the folded-over edges along diagonal lines associated with each corner. Elastic bands cooperate with each pocket to maintain the fit on the corners of the mattress. The bands are fastened in a stretched condition to the folded-over edges while the sheet is in a flat state. The process of the invention is particularly adapted to continuously forming such sheets which may be formed from a variety of inexpensive materials. Sheets of the invention are particularly useful in hospitals and nursing homes where frequent bedding changes may be needed.

  • Patent number: 4538312
    Abstract: There is disclosed is a reversible fitted playpen pad cover including an upper panel having a rectangular area which is the same as the area of the floor of the playpen; a lower panel having the same area and shape as the upper panel in which the lower panel is secured to the upper panel along three of four mutual edges of the panels. This arrangement leaves an unclosed edge between the upper and lower panels and, thus, defines a flexible closure therebetween. There is also provided a rectangular lip panel which integrally depends from the upper panel along the unclosed edge of the upper panel. The lip panel is folded into the volume of the closure between the upper and lower panels and, along its opposite left and right edges that extend from the line of dependency with said upper panel, is secured between the upper and lower panels. The width of said lip panel extends over about one-third of the width of the entire playpen pad cover.

  • Patent number: 4402098
    Abstract: A bed covering includes a fitted side covering adapted to overlie the head end, foot end and both sides of a mattress. A top portion of the bed covering overlies the top surface of the mattress and is connected to the fitted side covering by a folded skirt portion which extends along the foot end and both sides of the mattress. The skirt portion is folded along a medial lower edge so as to present an interior layer fastened along its upper edge to the fitted side covering and an exterior layer fastened along its upper edge to the top portion. The fitted side covering both secures the bed covering onto a mattress and tends to properly position the top and skirt portions relative to the mattress for facilitating the making of the bed.

    Abstract: A bed covering includes a top covering adapted to overlie the top surface of a mattress, a side covering adapted to be fitted to the mattress and to surround the head end, foot end and sides thereof, and a foldable side panel interconnecting the top covering and side covering along the foot end and at least one side of the mattress so that the mattress, side panel and top covering define somewhat of a sleeping bag type enclosure for receiving a person. A first zipper along the edge of the top covering and top edge of the side covering enable the bed to be made by simply closing the first zipper to thereby foldably collapse and enclose the side panel between the top covering and mattress. A second zipper may be provided between the side panel and side covering to facilitate entry onto the mattress below the bed covering.

  • Patent number: 4233701
    Abstract: A napped bedding blanket having an enhanced hand and a more uniform surface appearance and which substantially avoids the problem of shedding and pilling without chemical treatment or mechanical locking and thereby is able to substantially maintain its initial surface appearance during normal usage and after laundering. The blanket has a nap of uniformly distributed raised fibers on at least one side of a fibrous substrate, with the fibers extending generally outwardly from the substrate a uniform distance to provide a planar surface on the nap. The blanket is produced by subjecting a nappable substrate to a napping operation to raise fibers from the substrate and form a nap, and thereafter shearing the nap to a level such that substantially all of the raised fibers are sheared.

  • Patent number: 4187567
    Abstract: A waterbed construction having an inner rigid frame member and a supported flexible bottom member for holding and laterally supporting a water filled bladder or vinyl mattress. The inner rigid frame member and bladder are covered and interlocked by a cushioned "cap" having rigid side walls and a flexible top member. The cushioned cap fits closely over the inner rigid frame member in much the same manner as a cover fits over a box. This arrangement provides additional strength for containing the lateral forces generated by the water filled bladder and at the same time provides maximum sitting comfort. In addition, the use of a close fitting cap having outer rigid side walls in combination with an inner rigid walled frame member, provides a sealed container for the bladder and virtually eliminates the possibility of water loss in the event the bladder develops a leak.

  • Patent number: 4164797
    Abstract: A mattress construction comprising a filler with a surrounding mattress cover. The cover defines an opening along at least one of its ends, and a zipper is provided for closing the opening. A fabric section of the cover is positioned in overlapping relationship with one end of the zipper. This section defines a pocket for receipt of the zipper closure when the zipper is closed to thereby reduce the likelihood that the zipper will be opened during use of the mattress.
